Project Lifesaver utilizes radio direction finding in order to locate missing loved ones. A transmitter is worn on the wrist (in most cases) of Project Lifesaver clients. The transmitter emits a radio frequency signal / pulse once every second. The signal itself is not audible and can only be detected by a receiver.

The transmitter is powered by a battery that is changed by volunteers every 30 days. Caregivers are provided with a battery tester and are required to manually test the battery daily. This is easily accomplished by placing the tester against the Personal Locator Unit (transmitter). An operational battery will be indicated by a flashing red light.transmitterPLUPersonal Locator Unit (transmitter)
